Scenario/Summary

Karen was 68 years old and in good health. She loved to run and had competed in numerous marathons (26.2 miles) throughout her 40s, 50s and 60s. Recently, her primary care physician had cautioned her to slow down her running and take it easier on her body. Her physician, knowing that karen was unlikely to stop running altogether, suggested that she limit her running to one half marathon (13.1 miles) per month.

In March, Karen signed up for a half marathon and she eagerly awaited the start of the 7 am race. It was usually hot for that time of the year with temperatures reaching into the high 90s for the past several days. The temperature at the start of the race was already well into the 80s. She usually carried a water bottle with her on her races but this time, in her zeal to get to the race early, she forgot the bottle and left it at home. The first six miles went well but the temperature was starting to rise and Karen felt the effects on her strength and speed. Karen started to feel dizzy and tried to make it to the side of the street to sit down when everything went black.

Other racers notified the first aid station. Karen was shielded with an umbrella and sprayed with tepid water on her skin. Cool pads were placed on her forehead and neck. She was then transported to the local emergency room where the physicians diagnosed Karen with hyperthermia.

I. How does homeostasis relate to hyperthermia?

II. How does the application of cool pads and spraying of water on the skin lower the body temperature?

III. Why did the first aid volunteers spray her with tepid water instead of cold water?

IV. Did the lack of water to drink while she was running help or hinder her situation? Why
